Typically 10,000-15,000 km or annually, whichever comes first (specifics in manual).
Timing Belt Replacement:
Crucial interval, often around 60,000-100,000 km or 5-7 years due to catastrophic failure risk. Manual provides exact interval and procedure.
Spark Plug Replacement:
Intervals vary by spark plug type (standard vs. long-life Twin Spark), manual will specify.
Engine Oil:
Typically Selenia or equivalent specification API SL/SJ, ACEA A3/B3, viscosity 10W-40 or 15W-40 depending on climate. Manual specifies exact OEM requirements.
Coolant:
Ethylene glycol based coolant, typically Paraflu UP or equivalent, mixed 50/50 with distilled water.
Brake Fluid:
